TO2A J-11 Scaffolding Sample Task Order 2_Complex Visual Aide.pdf

This document is a technical specification and site plan depicting installation requirements for a platform and pipe hanger support system within a cavern housing a cryostat facility. The project involves four primary installation locations (#1-4) with specific dimensional and access constraints.

For Locations #1-3, contractors must install a full-length walking platform (195-205 feet total length) that cantilevers off the side of the cryostat to provide access to anchor points on the cavern north wall. The platform must be installed at a height of 81½ inches from the top of the cryogenic beams and must be anchored to the top of the cryostat. Critical access constraints include a distance of only 1-2½ feet between the cryostat side and the cavern north wall, with the cavern wall being irregular and non-flat, requiring flexible installation solutions. For Location #4, a sled system must be designed to anchor to the top of the cryostat beams with the capability to move downline to continue platform installation across the facility. Pipe hanger installations extend to a maximum height of 210 inches from the top of the cryostat. The site plans indicate complex spatial relationships among cryogenic beams (blue), piping systems (yellow, red, and purple), structural support elements (gray), and floor systems (red), requiring precise coordination to ensure installations do not interfere with existing equipment and utilities within the confined cavern environment.
